WHEELBARR OW FOR MEASURING FIELDS, 86C.

SPECIFICATION forming part of Letters Patent No. 673,300, dated. April 30, 1901..

Application filed May 31, 1899.

siding at Raab, and EMERICH TORKOS, resid ing at Liczko, Austria-Hungary, subjects of the Emperor of Austria-Hungary, have invented certain new and useful Improvements in Wheelbarrows for Measuring Fields and the Like, (for which Letters Patent have been granted in Austria December 19, 1898;" in Hungary December 6, 1898, and in Germany April 2'7, 1899,) of which thefollowing is a full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use the same.

The present invention relates to a wheelbarother surface can be quickly measured in a simple and reliable manner. With the assist ance of this wheelbarrow anybody, although not acquainted with engineering, can make measurements, and by the use of this apparatus all auxiliary manual labor, which is absolutely necessary when measurements are made by means of the chain or other instrument, may be dispensed with.

The invention is represented upon the ac com panying drawings,-u pon which Figure l is a perspective view of the barrow. Fig. 2 is a front view of the counting mechanism arranged on the barrow on an enlarged scale; Fig. 3, a back view of the same. Fig. 4 is a transverse vertical sectional view of the counter and alarm mechanism,the parts being in operative position. Fig. 5 is a similar view of the samein inoperative position, the dial being out of engagement with the screw-thread or worm.

The principal constituent part of this meas;

counting mechanism, by means of which the number of revolutions described by the wheel b is indicated. This counting mechanism consists of arotating dial fand indicatinghand g. The dial f is provided with teeth on 5 5 its periphery, which engage with the screwthread or worm h on an extension of the axle e. The screw-thread or worm it rotates with the wheel I), andconsequently moves the dial f, which is arranged beneath the fixed. indi- 6o eating-hand g. Division-marks are provided on the dial f, and the latter is moved through the distance between two of the marks upon the wheel b rotating once. The gear can, for example, be so chosen that one rotation of the dial f corresponds with a hundred revolutions-of the wheel I), in which case, of course, onehundred division-marks would be passed through on the dial. Upon the back of the dial f a triangular lug or projecting piece tis arranged in such a manner that it passes a circular openinglin the back part of the casing is upon every revolution of the dial, Fig. 8. A pin m projects through the opening Z, which pin is fitted toahammer m, supported bya spring-arm m. The point of thehamrner m rests... upon the inner surface of the hell 0, arranged on the back and out side of the casing of the dial. Now when the triangular projecting piecei passes the open ing Z the pin m on the hammer on slides upon the inclined surface of this triangular projecting piece to the-point-ofthe same and then falls suddenly, whereby the point of the hammer strikes upon the hell 0 and by this means indicates when a revolution of the dial f has taken place. The driving rods or bars a a are provided at the back with folding legs p.

When it is desired to measure the breadth 0 or length of a field, the barrow is wheeled over the distance in question. It is apparcut that the number of revolutions of the wheel I) will give the length passed over in the units of length arranged for. The num- 5 her of revolutions is ascertained partially by counting the number of signals given by the hammer m and partially by examining the counting mechanism. Each signal of the hammer indicates that as many units of length have been passed over as there are divisions on the dial f. By adding the number of these units of length to the units of length passed over since the last signal, which can be read 01f from the dial, the total units'of length passed over are obtained, whereas the fractional partsfor example,decimetersare indicated by the indentations of the ribs 0 upon the ground. From the .length thus obtained the superficial contentsof the ground to be measured can be calculated in the well-known manner. In order to facilitate the measurements, the dial f should always be placed at 0 before starting. For this purpose the screw-nut 'r, which presses upon the dial f, is pushed forward under the action of the spiral spring at, arranged beneath it, so thatthe teeth on the periphery of the dial can be r iou-r hands in: the presence of two Witnesses.

brought out of engagement with the screw thread or worm h and the dial can be turned by hand into the desired position.

Fig. 4 of the drawings represents the dial held in mesh with the worm, and Fig. 5 represents the dialv released from theworm in I In a measuring device of the character described the combination of a wheel 19, a worm h, acounting device comprising frame 10', pin '25, a dial provided with teeth on its periphery rotatably mounted upon said pinand in mesh with the worm h, astationary indicating hand or pointer an expanding spring n interposed between the dial and the frame adapted-t0 ;throw the dial out of engagement with the worm, and a nut rotatably mounted upon the pin and adapted to hold the dial in operative position substantially as and for the purpose 4o specified.
